As part of an audit, adds as much visible coverage from 73.4% to about 84.2%, but after #6668 is merged, we'll have it about 88.X% and the coverage report seems to show only missing cases of not common scenarios, e.g. a case that'll make jsonpb.Marshaling to fail, and which will return an error anyways.
